WHY DATA WAREHOUSE?

Because Excel doesn't scale with your business. Your data shouldn't block decisions.

Single Source of Truth

Stop chasing data across Postgres, Stripe, Google Sheets, and CRMs. One warehouse. All your data. Always up-to-date.

Real Analytics Capability

Complex queries in seconds, not hours. Historical analysis. Trend detection. Stop exporting to Excel for every analysis.

Don't Kill Production

Analytics queries slow down your app? Warehouse separates analytics from production. Run heavy queries without impacting users.

Automated Pipelines

No more manual exports. Data flows automatically from sources to warehouse. Fresh data every hour/day. Set it and forget it.

PROVEN APPROACH

Real project. Real results. This is how it works in practice.

HOW IT WORKS?

01

Discovery & Requirements

Critical phase: Deep dive into your data landscape with key stakeholders. Identify data sources, understand business questions, audit data quality. Define success metrics and align expectations. This foundation determines everything that follows.

Week 1 (Days 1-7)
02

Architecture & Initial Setup

Platform selection based on your needs and cloud infrastructure setup. Initial data model design with your team's feedback. First proof-of-concept pipeline to validate approach before scaling.

Week 2 (Days 8-14)
03

Pipeline Development & Testing

Iterative delivery: Build ETL/ELT pipelines incrementally, one data source at a time. Continuous collaboration with business stakeholders to validate data transformations. Regular check-ins ensure we're solving the right problems.

Week 3 (Days 15-21)
04

Refinement & Handoff

Final iterations based on stakeholder feedback. Data quality monitoring setup. Team training (SQL, data models, dashboards). Documentation handoff. 4 weeks of post-launch support included.

Week 4+ (Days 22-28+)
